Hi, I am running my application on device based on Compute Module 4S (Cortex-A72 (ARMv8) 64-bit ). On this device I installed RPi Runtime in 4.11.0.0 version. In my project I use device: Codesys Control for Raspberry Pi 64SL and my project works, but I actually do not have acces to all GPIO's , because GPIOs Compute Module is available only in 3.5.16.0 version and it doesn't work. Properly work GPIOs B+/Pi2 but using this device I do not have acces to all GPIO's in CM4S. Anyone of can tell me how add GPIOs Compute Module 4.11.0.0 to my project ?

Post by sigurdrb on send appliaction files to wago plc (codesys 3.5) via ssh

Hi, I was hoping I could send the two files "application.app" and "application.crc" directly to the directory "/home/codesys/PlcLogic/Application" instead of logging into the device with codesys, downloading the program to the controller and then do the "create boot application", so it will reboot with the correct program running. I think i also need to edit the file "eRUNTIME.cfg" located in the "/home/codesys/ folder, because when I create the boot application from the codesys IDE, these lines are added to the file: [CmpApp] Application.1 = Application [SysFileMap] /home/codesys/PlcLogic/Application/Application.app=0x212520, 0x2DBC747E, 2DBC747E.app I think the "eRUNTIME.cfg" file is the same as CODESYSControl.cfg I also dont know the purpose of the hexadecimal numbers etc. that is generated. When I tried to replicate what codesys was doing, I placed the same files in the same folder as when codesys generated the boot file. And also added the lines in the eRUNTIME.cfg file: [CmpApp] Application.1 = Application [SysFileMap] /home/codesys/PlcLogic/Application/Application.app The controller did not boot up with any program, so my method did not work at all. I guess these lines tells the controller to run an application and where to find it? Could any of you help me with the best way to get the compiled program to the controller without using codesys or wago-software?

Post by jaspergain on Non-existing identifiers
CODESYS Forge

(Post)
Hello, I got a bit of a weird issue going on which is kind of annoying. So recently we switched a lot of Modbus IO to EtherCAT, as we were having issues with stability. All works fine, which is great. But sometimes when I change the program I get errors claiming that identifiers are not defined. Meaning I can't go online. See the picture below. I believe this is because some of these identifiers were used with Modbus, and they weren't properly removed/deleted? A clean all temporary fixes the issue, but it comes back again after a while of changing the code, and building. Any way to fix these non-existing required identifiers, or even find out where they are required? Thanks for the help in advance. Jasper.

Ein Schrittmotor muss immer an einem entsprechenden Schrittmotor-Treiber/Kontroller betrieben werden. Mit welcher Spannung dieser Treiber versorgt wird(üblich von 5V bis zu 70/80V DC und mehr) und bei welcher Strangspannung der Nennstrom durch die Motorwicklung fließt, ist ein himmelweiter Unterschied. Genau das ist u.a. die Aufgabe des Treibers, die Spannung so zu regeln, dass die Motorwicklungen von dem aktuell notwendigen Strom durchflossen werden. Siehe https://de.wikipedia.org/wiki/Schrittmotor Stichwort Chopperbetrieb.
